BASEMENT AND LIKE VENTILATOR.

Specification of Letters Patent.

Patented April 24, 1906.

Application led January 2,1906. Serial No. 294.170.

To all whom t may concern:

Be it known that I, PETER H. J AcKsoN, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Basement and Like Ventilators, of which the following is a specication.

My invention relates to basement and like Ventilating devices; and it consists in a coinbination and arrangement of parts and details of construction, which will be more fully explained by reference to the accompanying drawings, in which- Figure l is a vertical section showing the ventilator open and the drain connection. Fig. 2 is a similar view with ventilator closed. Fig. 3 is a horizontal section. 4 is a vertical section of a modified form.

The object of the invention is to provide a simple and effective means for ventilating a basement extension or space under a sidewalk, yard, vault, room, or other similaiplace by the employment of an open ventilator fitting into the sidewalk or floor above approximately flush with the top surface, having its lower part opening into the room beneath which is to be Ventilated, with an annular or other shaped chamber adapted to receive water and dirt which may fall through the open grating in its top and discharge its contents through an opening' in the side of the ventilator as nearly as possible to its bottom through an attached short horizontal straight drain-pipe passing through a hole made into the curbstone out into the gutter, so that the dirt, mud, and water may pass direct from the ventilator into the street-gutter without clogging the drain-pipe- Vhere the drain-pipe is a long one and has one or more bends necessarily made to reach the drain-pipe of the building leading to the sewer beneath the street, the great length of pipe and elbow bends is liable to be lled with the mud and the ventilator value is inipaired.

This improved ventilator with open top for free ventilaton forms ready lodgment for dirt and mud that may be blown or tracked in and is usually placed on the outer edge of the sidewalk about two feet distant lfrom the gutter', and the short straight drain pipe forms a ready passage of the contents to escape to the gutter.

The curbstone portion forming the outer edge of the sidewalk in many places is but a rising from four to five inches above the base of the gutter, and this shallow depth necessitates making the ventilator of correspondingly slight depth. Also allowance has to be made for a slight inclination of the pipe from the Ventilator to the gutter that the water m}a1y run off through as large a pipe as possi) e.

To make the ventilator of such slight depth that its contents may be run oil'l into the gutter and not become stopped and overflow into the room beneath, and maybe freely opened to ventilatie, and may also be closed at will to keep out cold, is the novelty of this device.

The large opening in the top grating of ventilators for plentiful ventilaton admits a` large quantity of dust and dirt being blown in, which when undisturbed during rain and after beingl dried by the sun becomes hardened, and it is necessary to break up or cut up the dried mass that it way be washed away by water from a hose played through the top grating and down into the streetgutter, and as there is no means of cleaning out the inside annular gutter of the ventilator by hand I have devised an extended horizontal blade or blades attached to the side of the revolving rim, which upon being screwed up rises and closes ventilation, and when screwed in reverse direction opens ventilation. The action in turning this sleeve by hand makes the extended blade circle around and rise or descend in the open gutter, slicing off the dried dirt and mud contents in and above the gutter, and with the plow-points extending down from the blade plow furrows in the mass, cutting it up in small pieces, so that it may fall by gravity or be washed away out by water into the street-gutter.

A is the casing, having a flange adapted to fit in a corresponding rabbet or depression in the sidewalk to which it is fitted and having an internal annular seat upon which the rim of the ventilator is adapted to rest, the upper surface being approximately flush with the rim of the casing and with the surface in which it is seated.

IOO

The sides of the casing A extend downwardly to the desired shallow depth, which is shown to be not below the bottom of the street-gutter, with an annular bottom at 3, within which it forms an upturned flange 4, forming a channel of any suitable or required de th.

lnterior to the rim 4 is a central opening communicating with the space below. This portion is preferably cast in a single piece, thus making an economical construction.

To the center of the ventilator-cover 2 a brass, copper, or steel screw-bolt 5 is attached and extends ldownwardly beneath the grating, as shown.

6 is an annular 'rim that nicely fits outside of the rim 4 and of suitable depth to close the opening when it is elevated into contact with the cover 2, as vin Fig. 2, and when lowered to the bottom, as in Fig. l, it leaves sufficient opening for ventilation over its top. Upon the top of this rim on its inner portion are formed arms 7, their inner ends having a hub 8, which extends down and forms a threaded sleeve which revolves on the screw-bolt 5, so that when the rim 6 is turned it revolves and is eitherraised or lowered, according to which way :it is turned. When elevated, it closes ventilation, and when lowered it leaves the opening over its top for ventilation. The lower end of the hub or sleeve 8 may be provided with projecting lugs 9.

A bifurcated hook 10 is fitted with a handle of suicient length, so that the hook portion fitting over the lugs 9 allows the rim 6 to be turned by a person standing on the basementfloor below, and it will be seen when turned in one direction the rim will be lowered and leave an open space for free ventilation over its top, and when elevated it will close ventilation.

U on the outside of revolving rim 6 a blade or b ades 11 may be formed or attached, extending out from the sides of the rim. These blades may have vertical portions 13 extending downward at any desired distance, by which means when the rim 6 is turned by means of the bifurcated hook the rim and blades will revolve with it and slice off and cut furrows in the hardened mud or prevent caking, breaking up the dirt, so that it may be washed down the drain-'pipe into the gutter.

On the under side of the open grating or ventilator is formed an annular flange 14, which forms a guide and directs the water, dirt, or dust that may come through the top of the ventilator directly into the channel beneath for its reception, deflecting it outwardly and preventing its passing into the basement.

The shallow depth of the street-gutter, which is but four or five inches in depth, forbids the use of a deep ventilator, such as in my former application, where a 'cone of proper depth is used to deflect dirt and water into the channel in the bottom of the ventilator.

The grating-cover 2 of the .ventilator has openings only through it on its outer portion,

'so that water Yo r dirt cannot fall into the central connection with the basement.

Fig. 4 is a modification showing the outer surface of the rim 4 screw threaded, and upon the inside the revolving rim 6 is also a screw-thread, which fits into the threads of the rim 4.

Two-projecting lugs 9a project from the outer rim upon which the bifurcated forks of handle 10 fit. This dispenses with the screwbolt and sleeve in the ventilator-cover.

Having thus described my invention, what I claim, and desire to secure by Letters lPatent, is-

l. In a vault and like ventilator, a casing fixed in the covering-surface and having a closed bottom, a central upturned open flange and a perforated top cover, an open-ended sleeve turnably mounted on the outside of said flange and operable in the casing between the bottom and perforated top cover, and means by which said sleeve may be raised to close, and depressed to open the ventilating-passage..

2. In a vault and like ventilator, a casing fixed in the covering-surface and a cover therefor having its central portion closed and the outer portion perforated, said casing having an annular closed bottom and a central upwardly-extended open tube, a rotatable vroo sleeve surrounding the outside of the open tube and having its opposite ends contained between the closed bottom of the casing and the cover, and a screw by which the sleeve may be raised into contact with the center of the cover and close communication, or depressed to open it.

3. In a vault and like ventilator, a casing fixed in the covering-surface and a cover therefor, having exterior openings and a closed center, a closed annular bottom to the casing with an outward -discharge pipe, a central opening with upturned surrounding flange, a sleeve turnably fitting and vertically movable upon the flange, and arms or plows projecting into the annular chamber and turnable' with the sleeve.

4. In a vault and like ventilator, a casing fixed in the covering-surface, a cover therefor having exterior openings, a central closed portion with a circular flange extending down from its lower surface, an annular closed bottom to the casing, withva central opening and an upwardly-extending surrounding rim, a sleeve turnable and vertically movable upon the rim, and closable against the cover-flange, said cover-flange being concentric with and adapted to inclose the upper end of the turn- IIO coincident with the cover-flange, and a sleeve movable on said riin and elosable against the cover interior to the flange thereof.

In testimony whereof I have hereunto set 15 Iny hand in presence of two subscribing witnesses.
